Solar Fan STEM Kit Challenge

[vc_row][vc_column][vc_column_text] Introduction A solar cell can convert energy from the sun into electricity. This kit has some basic parts to build a solar circuit. Put on your experimenter’s hat. Remember to make a complete circuit (a circle). Also remember to connect the bare metal ends of the wires. The insulation around the wires will stop the electricity.     How do solar cells work? Solar energy is a type of electricity created from the light rays of the sun. Current technology harvests these rays using a panel of solar cell wafers containing two different layers of silicon. One layer (called n-type, high in negative charge) contains an excess of electrons,...

Two students hold their solar spinners - solar panels glued to petri dish lids - underneath a high-intensity lamp.

A single cell consists of a slab of silicon (single crystal or polycrystalline) with a continuous metal collector on the back and a grid contacts on the front which are necessary to collect the current from the wide area of the cell because silicon is a semiconductor which has a relatively...
